Sda speaker placement

boston1450

Attachment not found.(SDA1c) Room size is small 15 - 12 so small room anyways. As you can see from pic all cords are hiding in floor. Big plus. I have speakers 6ft 3inches apart----7 inches off wall.....each speaker is at least 3 ft from any wall. But the amp is between them-closer to the right one because of office door ive read about placement many of times here. I can bring them apart a bit more--what do you think ? --leave them 6'3 apart or spread the right one more to the right some to give it space from amp----i am temporary storing my 2b's in the same room till i decide where im put them/or store them for rotation & future upgrade

spikes make a substansial difference...try bringing them from 7" off the wall to more like 15" and then sit back for awhile and see what you get...just make sure the distances are equal for each spk and square to the wall..nice rig! i have a 555 with my 2btl's:)

I can pull them out when using them & try. Wife probably wouldnt like them that far out as there isnt much room to walk through. We have couch & recliner on other wall. Small rooms svck-but i'll give it a try. Thanks

boston1450

Yes the 555 does a wonderful job with these. I am looking so forward to upgrading the 2b's. i just replaced one of the sl2000 on the 1c's im not sure what happened but it wasnt working

The bass is supposed to be better with the placement you have now re: distance from the back wall. I would think primary importance is to have them at least a couple of inches in front of the equipment rack so imaging is not affected. But if you move them too far away from the back wall it may have too much effect on the bass.I agree with sda2mike, though. Move them around a little and see how it sounds. Also agree that spikes improve the sound quite a bit.



Gotta say that mine are not optimally placed due to room issues and they sound phenomenal. Course I have to use a subwoofer to fill in the bottom, but it blends seamlessly. Play around with it and I'm sure you'll find something that works and has an acceptable spousal approval factor

That looks OK to me. You can experiment with pulling them out as mentioned above but that will probably decrease the bass output a tad. Mine are not currently in rotation because the only room I have that has more than the minimum requirement of 14 continuous feet of free space is my basement which is about 20 x 10.5 and I have a built in down there that is currently housing an old Toshiba 27" tube set, two Boston Acoustic A100s, a Csi-3 center, a Pioneer AVR and a Pioneer SX-3900 which is running two Original large Advents that are on the floor to the side of the A100s. There is also a Pioneer SX-838 on the floor along with a LAB 395 TT that sits on it, and some EPI 100Vs that are being run by the Pioneer SX-838 (a very "sweet" sounding combo) that sit on the Advents. It's pretty crowded down there. And there are other pieces around as well. lol

At least you have some decent space in a "real'' room here!

Have fun. I also have an Adcom GFA-555 that is also not currently pulling any duty--good reserve power when you need it!

Thanks for all feedback. Ive been playing with placement today. It makes it hard in small room like this. I moved the SDA2b's to a different spot to store & brought the right speaker more to right & out some-past the amp rack. Sounds very nice but probably not wife friendly. Thank god i have other systems & can move these easy enough when the misses isnt around

I had 1C's in a smaller room than you've got. Acoustic treatments made a huge difference. Also not very wife friendly, but the improvement was staggering.

my wife feel in love with this house because the kitchen & dining room. I hate it because we sold our 16+ by 24+ living room in our last house. She's all good with my music hobbie to a certain extent. so i make it by till i get the upstairs 2 bedrooms my daughter has her ''PAD''in..

boston1450

Ok. Bare with me---- ive spiked my Vandersteens i use to have. But i didnt know these SDA's can be spiked. There must be some Pro's n Con's on doing this ? Is it better to have them spiked/far more rewards to doing this ? Should i wait till i put them on carpet upstairs when i have room for just this system ? All feedback will be appreciated. Thanks

Spikes make far less difference on a hard-surface floor than they do on carpet. Spikes are practically mandatory on carpet, especially thick carpet with a heavy pad underneath. Far as I'm concerned, there's little point (!!!) to spiking speakers on a hardwood floor, and it saves the floor surface. Beware using spikes and then protecting the floor with some sort of shield or cup. The shield or cup does the exact opposite of what the spikes are supposed to do, meaning that you just spent twice as much money for essentially zero net gain.

Any speakers can be spiked. A matter of drilling holes for thread inserts, (if required) and **** the spikes into the bottom of the speaker cabinets.

Ive seen some Bigger SDA's that were on a platform ? & figured they were spiked. I wont be doing it on the floor they are on now. But when they go upstairs i will spike them....wasnt sure because a few above said spike them ? Thanks

We have a similar layout. my SDA2b are 7' off outer corner to outer corner front firing w/ no toe in and my seating pos is 9' from center which is close the equilateral triangle I can get.I also have them 14'' from the back wall and like you on a hard wood floor. I run an Adcom 555 and love the combo.

leftwinger57

I've heard of spikes to prevent the speaker from sliding on carpet and they are meant to pierce all the way through till it hits floor.Wood on wood seems to be just abrasive enough to hold fast and I have not seen any movement from my speakers.Vandersteens are totally different animal and Richard Vandersteen says you must use the anchor stands and they need to tilt up so you get what ever effect w/ his tweeter and delay he's looking for.

Randy, that small, fairly open rack is not going to be a problem, so don't even worry about it. Leave your speakers close to the back wall, 2 feet out is way too far. The general guideline is 5 to 6 inches off the back wall. Spike them even if you have to use spike discs on the wood floors, they do make a positive difference.

nooshinjohn

In such a small space, I would try and set then to exactly three feet from the sidewalls and 6 inches from the back wall.

boston1450

Attachment not found.Cool. I tried bringing them out some but cant & didnt notice too much difference. I have them back at 7 inches from back wall & it seems to work well--they do not move at all--i did bring rack over 3 inches to the edge of door opening to get it away from side of rt speaker & sounds great. (Hard to do as i have wires/cord going through floor into basement) I sit about 10ft in from to them centered(perfectly)& its the best i can get it in this room. Thanks again all-time to enjoy them more

that how original sda brochure placement says too & thats how i had them & it seems to work well. I measured 7 because i wanted to get more past that rack. Stinking door screws it up. Lol

Thanks on spike tips

does that improve BASS or what would that improve. I may have some spikes in my garage BUT
..
1) are there certain ones i should be using. If you have a reference i can order some. I should have all the necessary tools to do the job
2) spike disc ?
Not cheesy ones at hardware store. Lol

F1nut

They will improve the bass and also clean up the mids.

Brass or stainless steel are my choices. I don't know what you want to spend, so pick something you like in your budget. Parts Express sells the Dayton spikes for not much money. Adona and Via-Blue offer more choices. Track Audio and HiFi Racks, both in England offer really high quality stainless steel spikes. Spike discs are small metal discs you put under the spikes to protect the wood floor. Any place that sells spikes will have them.

I used these on my 2As, and all three subs:

Forgot the photo. I beg to differ, the spikes and cups make a dramatic difference on wood floors. The cups do not negate the effect the spikes at all.

Thanks for the pic & site info. Ive been to Parts Express site--those ones on the bay look nice

I am aware of how far off the back wall to place my SDA IIb speakers however the room I have them in is 15 Ft. long and 8 Ft. wide. I have the speakers placed on the 15 Ft. wall about 2 Ft. 6 inches off each side wall and there is about 7 Ft. 6 inches between them. The right wall is solid poured concrete block. The floor is solid poured finished concrete. The left wall is drywall unfinished on the side the speaker is on. The floor has very thick roll out rug (throughout the room) . I have them sitting on concrete blocks that I painted black with Armaflex adhesive as padding on the top of the blocks. I know this is an old thread just did not think it was the right thing to do to start another as this thread has a lot of the same information, so hope someone sees it (F 1, westmassguy,drumminman) ..Any suggestions ?? Thanks !

F1nut

Get them off the blocks and if you haven't yet, install spikes.

VSAT88

Will do. Thank you
